I feel the 70-300L/5D3 is best supported by a tripod collar, due to its combined weight. I bought a $42 version from China off eBay. It was delivered very fast (less than a week) and is of decent quality, but the clamp tolerance was a little loose. I fixed it by shimming the gap directly beneath the hinge with a 1-inch long piece of 3/4-inch velcro (loop/fuzzy side). This took up the slack while still allowing the lens to freely rotate for vertical shots and doesn't leave any messy, sticky residue, like tape would when it gets hot outside. It's been working great for months, now, so for $42-delivered, I'd say it's a much better deal than Canon's collar. Here's the link, if anyone wants to check it out:

Unless you wish to use a tripod all the time (except when doing flight photography), your choice is between the 100-400 IS and the 300 f/4 IS. It is a tough choice. Good luck making it
